Excellent Product
27 Aug 2014
By Niki
, Bath
"Surprisingly easy to apply. I used a roller and obtained a good solid smooth coat. I was very impressed with the final result. Good and solid in a few hours and proved to be an excellent base for emulsion. The only warning on this is that the stated coverage is somewhat optimistic. I used 2.5 litres to cover a 5m wall. That's about 5m² per litre, not the stated 7m². Certainly did the trick though and was well worth the expense. No sign of any marking to date. This is an excellent, easy to use product."

Damp Seal
28 Feb 2014
By Anonymous

"First time I've used this product. Been struggling to cover damp patches on an internal wall. Dubious to start but so far so good.
Apply liberally as instructions, but you will need to lay off a few times as the product dries to avoid sags.
All spots that initially bubbled up dried back rock hard and did not open up.
Then easily over painted with emulsion and whole wall dried consistently and no dark damp patches.
Permanently in the van now!

Does the job, but pricey
10 Nov 2013
By IKAR
, London
"Bought this product to cover stubborn water stains from a previous leak.
Does what it says on the tin, however very thick to apply so has to be applied with a brush which makes application time consuming if applying to a large area.
None the less the item works although a bit pricey.
would still recommend."

Damp sorted fast
3 Oct 2008
By Speedster

"Great product to sort the problem fast.
Couldn't be more easy than roll it on the wall, after you have eliminated the cause of the problem.
Ideal if you have no cavity.
Checked with the damp meter and a greatly reduced reading was given.
Best way to apply is with gloss 4" roller for speed and best coverage and where a glove as it doesn't wash off !!
